剤処理を行い、印刷パターンを形成する。The material of the printing screen is an ultrafine wire such as metal typified by nylon, tetron and stainless steel. This printing screen is subjected to emulsion treatment on the stainless wire of a stainless screen composed of a net in which ultrafine wires are flat knitted to form a printing pattern.

メッシュの開口率が重要となる。There is an air gap between the wires such as nylon wire, tetron wire, and stainless wire, and the opening ratio of the air gap is called the opening ratio or the space ratio, and the mesh is the wire of 1 inch. Although the number of lines is shown, the printing thickness printed by the printing pattern of the printing screen is determined by the mesh opening ratio, mesh thickness (mesh thickness), emulsion thickness, ink viscosity, etc. If you want to print
The aperture ratio of the mesh is important.

のが実状である。Conventionally, it is generally considered that a printing screen has a mesh knitted on one plate at a uniform aperture ratio, and a printing film having a uniform thickness is formed by printing once. Regarding the printing thickness, the actual situation is that the end of the printing surface printed with the printing pattern has a convex shape and a flat printing surface cannot be obtained.

目的とする。As shown in FIG. 7, when an electrode paste such as a printing ink or a conductor paste is printed, the printing surface 1 at the end of the printing pattern on the alumina substrate 5 is printed.
Has a drawback that it is difficult to obtain a flat printed surface. In addition, since it is not possible to control the ink discharge amount partially, when intentionally forming a pattern with unevenness on the same plane, it is necessary to use multiple printing screens and overcoat to eliminate unevenness. there were. Alternatively, when the printed material is multi-layered, there are gaps inside the overcoat due to variations in the electrode thickness, which causes problems of internal defects such as delamination.Printing is performed several times to maintain the flatness of the printing surface. However, the printing efficiency is poor. SUMMARY OF THE INVENTION In order to eliminate these drawbacks, the present invention has an object to provide a method for producing a printing screen which requires only one printing to maintain the flatness of the printing surface.

関係を表1に示す。Using this press die 3, as shown in FIG. 2, the stainless wire 2 of the stainless screen is pressed in the direction of decreasing the thickness of the stainless screen under a pressing pressure of 1000 to 3000 Kg / cm 2. It was The opening 4 can be arbitrarily changed so that the portion 4 compressed by the press die 3 is pressed to squeeze and spread the stainless wire 2 and to be seen in the void 6 having the changed opening. FIG. 2 is a sectional view taken along line AA of FIG.
Further, the width of the printing surface 1 of the aluminum substrate 5 in FIG. 7 is about 2 to 3 mm, and the width of the convex shape of the rising printing surface is 1 m.
At about m, the press die at the portion corresponding to this portion is made convex and the stainless wire is pressed. As a result, the mesh thickness was reduced, the stainless wire was crushed and expanded, and the porosity was reduced accordingly. The obtained stainless screen was stretched on a frame by a commonly used method, and then a printing pattern was formed with a photosensitive emulsion. An Ag-Pd electrode paste was printed on an alumina substrate using these printing screens. Table 1 shows the relationship between the press pressure, the mesh thickness, the aperture ratio and the print thickness.

By using these printing screens, it is possible to control the aperture ratio and the ejection amount of printing ink by the press pressure. Also, when the circuit wiring pattern is printed using the screens of A, B, and C in Table 1, the cross section of the pattern end portion seen in the conventional printing screen disappears, and as shown in FIG. A flat and good printed surface 1 on the aluminum substrate 5 was obtained.
